` miniemen 'inea seafuary lo facture of suchboxe's ises -follows, first to nail a side and end of the box 'together with -a rightfangle .'oint to form one' corner ofthe box;-then to olikewisie with the other side and end'of the box; nextto: assemble the tivo l ljight-angle'part-s', thus mode, into rectngular form and nailthemvtog'ether :at one yfree or unsecured corner then to nail the saine together at therenaining free 'oi' unsecured'co'rner to complete the rectangular Aframe of the 2o box and thereafter to 'apply the bottom of the box to the freine in inverted position land lto neil it siinultneously t'oone sideand Oile end of the box; and lastly to' nail thebottoin si- -inultaneously to the other spideland end'of the box to complete its construct-1on.= Y, This custornal'yfptcess not only involvesmany steps, but is cumbersome an unsatisfactory on account of the separate handling thereof; before all vof the parts of the box are finallyv brought together and secured in iisseinbled relation. f

By means of' the ,presentinvention, kthe handling of the parts is reducedy to a minimlim, Y'the'vario'us sub-assemblies are `obvia.ted,fand vthe separateparts; composing the Y box are :lll secured together inthe first step voir' the process in preliminarilyassembled form, and mav be conveniently'handled its 40 aunit in that form untiland during the 'final Vassembly and completion of the box.

According to my, invention ythe process of melting trboxrom` its separate component partsfsuchgasa vbottom l, two `sides Zand 3, j andtwo end s 4 and `5', isi-.as followszz f of the parts and ofthe various subfas'selhblies The bottom l is nailed as indicated at 6 simultaneouslyito each ofthe eides vQ 3' and ends 4 and' 5, whille these verriuspazrts are `s'el'arate from each otherendfrfire held in the positions which theyoc'cupy in the coinpleted box and in which thebottomfextends y across and abuts 'against .the edjucentv edges bottom', as is usuel'l for?v instance, iIi eigr boxe-S; but. there nst-imneeeeeary-lf. f Y `1 The bot-tom;l sides endend-s moy be held in ltheir resp-eeuw pesetas by being fitted 'te a forni, engaged ablemanner. .A l y The` simultaneous kmitine?jet the bottom te granges;A or nyfother 'snit- Fig-..2 4isti perspective viewillustra-ting the eheh of the lsides and endsfmy bek coomplished by any appropriate nailing mechanism, as will be apparent to those skilled in the art. As the bottom extends across and abuts against the adjacent edges of the sides and ends, the nails are driven through the overlapping portions of the bottom and into the respective sides and ends, in the same direction, whereby to simplify this step and permit the simultaneous driving of the nails to be conveniently accomplished. Y

In Fig. 2 of the drawing two nails 6 are shown as driven through the bottom into each side and one nail 6 into each end, but it will be understood that this is merely for theV purpose of illustration and that the number of nails may be varied to suit the size and purpose of the box, provided there is atleast one nail so driven into each side and end.

As a result of this first operation or step in the process, the sides and ends are each separately secured to the bottom, although left free from each other, and a preliminary assembly is produced in which all of the parts are held together in substantially the positions which they occupy in the finished box. Notwithstanding the fact'that the sides and ends are Aseparate'froin each other and thecorners of the box free, the nails 6 hold the parts in association and permit the preliminary assembl to be handled as a unit until and during t ie completion ofthe box.V The preliminary assembly may thus be withdrawn from the form lor gages or other holding means and will still retain substantially the shape of thefinished box.

It is to be noted that in this preliminary assembly the sides and ends, being free from each other, will yield .suiiiciently relativelyone to the other to permit their being trued up, as may be necessary in the subsequent part of the process to insure obtaining a perfect product.

To complete the box, the corners thereof are fastened by nailing togetherv the meeting extremities of the sides and ends. This may be accomplished in two steps, as illustrated in Figures 3 and 4, respectively.

Referring to the stepV illustrated in Figure 3, both corners ofthe box adjacent the end 4 thereof are simultaneously nailed, as indicated at 7. As each end of the box extends acrossand overlaps the adjacent extremities of the sides, as above pointed out, thenails 7 at these two corners are driven through the overlapping port-ions of the end 4 and into the respective sides 2 and 3. By virtue of this arrangement, the nails 7 are all driven in the same direction and hence may be conveniently driven simultaneously at both of these corners of the box. Thevsimultaneous driving of the nails may be effected by any suit-able nailing mechanism, as will be apparent to those skilled in the art. The number of nails 7 driven at each corner will, o-f

course, depend upon the size and require-` ments of the box', although in the present instance three are shown for the sake of illustration.

The next step is to fasten the remaining unsecured or free corners of the box, that is the corners adjacent the end 5, by means of nails 8, which are simultaneously driven in both corners similarly to the step last described, whereby to complete the permanent assembly of the parts and to produce the finished box illustrated in Figure 4.

It is to be understood that instead of the last two steps above mentioned the box may, if desired, be completed from the preliminary assembly in one step in which the various nails 7 and 8 are simultaneouslydriven at all four corners.

The withdrawing of the preliminary as-V sembly lfrom its holding means, and its capacity for being handled `independently thereof, as a unit, pending, and during, the

lfinal completion ofthe box, are of imporsity of the holding'means, which is a part ofv the first machine, being transferred with the preliminary assembly to such subsequent machine or machines. With the present invention there is, therefore, greater economy and efficiency, a more rapidflow of work, and an increased output.

The insetting of the sides from the ends of the box, as above referredto, is to accommodate a lid or cover, but the invention is not limited to the making of boxes of that form, or to boxes having covers, nor does it relate to applying the vcovers where the same may be used'.

Furthermore, while the invention has been shown and described in connection with a rectangularboxhaving two sidesI and two ends, it may obviously be employed in producing boxes of other forms.

Various changes may be made in the steps i of the process within the scope of the invention, as defined in the appended claims.

Having thus described my invent-ion, I

claim and desire to protect by Letters Patent of the VUnited States: Y

1. The process of making boxes which consists in nailing thebottoin to the sides and ends while such parts are separate from each other and held inthe positions which they occupy in the finished box, and thereby forming a preliminary assembly, and withdrawing such preliminary assembly from Athe specially i holding means,'wliereby to permit suoli as-f sembly to be handled as a unit and shifted to convenient position for furtheroperation 'Without necessitating the shifting of such holding means. v

2. The process of making boxes which consists in nailing the bottom to the sides and ends While such parts are separate from each other and held in the posit-ions .which they 10 occupy in the finished box, and thereby forming a preliminary assembly, withdrawing such preliminary assembly from the holding u means, as a unit and shiftingit to convenient position for further loperationWithout shifting of the holdingmeans, and subsequently securing? togetherv the meeting-extremities of the sides andV ends to complete the box.

In testimony whereof, I have signed my f name to this specification.v
